With the quick development of modern industry, there is an obviously growing demand for energy. However, at present the available Conventional Energy Sources are decreasing day by day. The energy is a key factor for human being’s survival and it’s also important for the society’s development. Among the consumption of energy, the petroleum resource can supply nearly 90% primary energy source; the petrifaction resource includes coal, petroleum and natural gas etc. During the process of energy transformation, they can bring with a great amount of air and solid pollution, which can affect people’s health badly. The abnormal change of climate, the global warming and desertification etc all attribute to the released gas from greenhouse. They also affect the sustainable development for human beings. Besides, we realize that from the standpoints of development and overall situation, the lack of petrifaction resource is the basic matter to confine the future energy sources’ development. According to the prediction of some specialists, the coal can be use for 221 years, the petroleum is 39 years and the natural gas can only be used for 60 years! How to realize the sustainable development for energy sources, so that which can ensure the sustainable development for economy and society is the essential and crucial problem lying in front of all nations’ governments, that is the matter of energy sources strategy. The only way to solve it is unitizing the conventional energy sources as per arranged, economizing energy sources consciously and developing the new and renewable energy sources quickly. 
    The new and renewable energy sources include: the hydro energy, the wind energy, the solar energy, the biomass energy, the geothermal energy, the solid waste substances energy, the hydrogen energy, the nuclear energy. The above mentioned energies all belong to the low carbon and non carbon energy, which are important part for the future energy sources system. They have little even non pollution to the surrounding environment. China is abundant in new and renewable energy sources, comparing with the petroleum energy, its future is very promising. As a fast developing nation, china is now facing to the tough mission, that is the economic development and environment protection. In order to protect environment realizing the sustained growth on economy, to change the way of producing and consuming energy, so it’s the necessary choice for us to develop and utilize the new and renewable energy sources.

Following are some kinds of use for new and renewable energy sources:

The hydro energy: using hydro energy to make power.
The wing energy: using it to uplift water, assistant voyage and make power 
The solar energy: the heater, the desiccators, the greenhouse, the solar cooker, the warm supply, refrigerating, the desalination of sea water, the power generating. 
The biomass energy: the fuel, the power generating
The ocean energy: the power generating
The geothermal energy: heating supply, the greenhouse, the power generating 
The solid and waste energy: reducing the utilizing of the waster substance, the power generating.
The hydrogen energy: for burning and power generating
